Bond Work Index Procedure and Method

Jun 06, 2015  The Bond grindability was calculated to be 1.21 g net undersize/revolution by averaging the results from the last 3 runs on the Bond Mill. The grindability is defined as the ease at which a mineral particle is reduced to a predetermined size and used to calculate the Work Index. The feed and final undersize particle size analysis as well as the ...
